“A nice steep trail up the Great Blue Hill to the observation tower.
— Ron Birk
Lots of rocks and roots. Also some slabs.
The trail starts at the trailside museum parking lot and follows red markers. Right away it gets steep with stone steps and slabs. Halfway up the Great Blue Hill you cross a local road. The trail evens out for a bit here but immediately gets steep and rough again till you reach the top. This is where the observation tower is located with magnificent views.
